| description | The invention discloses an optimal design method of a large air compressor unit based on vibration analysis, which comprises the following steps: detecting vibration intensity, obtaining a power spectrum and a coherence function, performing coherence analysis, and calculating the frequency fx of a vibration signal causing the vibration of an air compressor to obtain main factors causing the vibration of the air compressor. Noise reduction processing is conducted on the vibration signals causing vibration of the air compressor unit, and feature extraction is conducted on the vibration signals obtained after noise reduction through a non-stationary signal analysis method. Then, vibration models of the large air compressor unit, the unit base and an oil platform where the large air compressor unit and the unit base are located are established in ANSYS workbench software, the frequency fX'and the maximum vibration peak value MX 'of vibration signals obtained after noise reduction are input, vibration simulation a |
